A total of 19,781 insect individuals belonging to 959 morphospecies, 145 families and 15 orders were collected. The most abundant orders were Diptera (69.68%), Homoptera (11.19%) and Hymenoptera (10.10%). At the family level, Chironomidae (17.67%), Mycetophilidae (12.32%), Cicadellidae (8.32%), Ceratopogonidae (7.56%), Sciaridae (7.39%) and Cecidomyiidae (5.81%) were the most abundant taxa.
